I did that awhile back, my Tinkerbelle asks for treats constantly and Whiska Lickin's were her favourites, Temptations ran a close second. I also noticed tartar beginning to buildup, (I have four persians)

I completely cut her off and replaced those with Royal Canin Oral Sensitive 30 as treats for all of them. It's designed as a diet but I already give them Royal Canin Persian Forumla.

I've had really remarkable success, they all like the Oral Sensitive, and still think it's special as a treat and the tartar is under control. I even saved some of the Whiska Lickin's containers and fill those with it, lol.

They are smart, but I am smarter.

Oral Sensitive is fairly new, it came out a couple of months before Christmas last. It claims to address oral hygiene, hairball control, and reflux control.

So far so good!
